func assertInEventLoop(file: StaticString = #fileID, line: UInt = #line) Asserts that the current thread is the one tied to this EventLoop. Otherwise, if running in debug mode, the process will be abnormally terminated as per the semantics of preconditionFailure(_:file:line:). Never has any effect in release mode.
func assertNotInEventLoop(file: StaticString = #fileID, line: UInt = #line) Asserts that the current thread is not the one tied to this EventLoop. Otherwise, if running in debug mode, the process will be abnormally terminated as per the semantics of preconditionFailure(_:file:line:). Never has any effect in release mode.
func assumeIsolated() -> NIOIsolatedEventLoop Assumes the calling context is isolated to the event loop.
func assumeIsolatedUnsafeUnchecked() -> NIOIsolatedEventLoop Assumes the calling context is isolated to the event loop.
